I commuted throughout the entire winter and these tights were brilliant. They fit great and did not roll down at all. They fit a little high so my back didn't get exposed to the cold. There were several mornings where the temps were 0*F and with a base layer and these tights my legs stayed warm. My only complaint, which isn't really a complaint, is that I am very tall and they were a little short. These are the best tights I have owned
